Description

Technical Field

[0001] This invention relates to the field of power maintenance technology, and more specifically, to a device for repairing broken strands in overhead ground wires. Background Technology

[0002] An overhead ground wire generally refers to one or more conductors at the top of a power transmission and distribution line, also known as a lightning protection wire. It is a conductor directly connected to the ground. Due to the shielding effect of the overhead ground wire on the conductor and the coupling effect between the conductor and the overhead ground wire, the chance of lightning striking the conductor directly is reduced. When lightning strikes a tower, a portion of the lightning current can be diverted through the overhead ground wire, thereby lowering the tower top potential and improving the lightning withstand level. Common overhead ground wires are often made of galvanized steel stranded wire, aluminum-clad steel stranded wire, or fiber optic composite ground wire.

[0003] Because overhead ground wires are exposed to wind and sun for a long time, fatigue cracks will appear when the stress or vibration reaches a certain level. Over time, this will cause the strands of the stranded wire to break, become unravel, or break completely. When the conductor is subjected to a large local current, such as a lightning strike, it is also prone to melting, resulting in broken or unraveled strands.

[0004] In related technologies, maintenance of overhead ground wires requires manual handling and can only be carried out after a power outage. This is not only highly dangerous, but also time-consuming, labor-intensive, and inefficient. Summary of the Invention

[0005] The main objective of this invention is to provide an overhead ground wire strand breakage repair device to solve the problem of low overhead ground wire repair efficiency in related technologies.

[0006] To achieve the above objectives, the present invention provides an overhead ground wire strand breakage repair device, comprising: a mounting frame having a concave portion at its bottom; a drive structure disposed on the mounting frame; a first gripper disposed on a first side of the mounting frame, the first gripper including a first connecting rod and a second connecting rod, the second connecting rod including a first rod segment and a second rod segment, the first rod segment and the second rod segment having a first preset included angle, the first end of the first connecting rod being hinged to the mounting frame, the second end of the first connecting rod being hinged to the end of the first rod segment away from the second rod segment, the end of the second rod segment away from the first rod segment having a first bent section, the first bent section being located below the mounting frame; and a second gripper disposed on a second side of the mounting frame, the second gripper including a third connecting rod and a fourth connecting rod, the fourth connecting rod including a third rod segment and a fourth rod segment, the third rod segment and the fourth rod segment having a first bent section. The device has a second preset included angle. The first end of the third link is hinged to the mounting frame, and the second end of the third link is hinged to the end of the third rod segment away from the fourth rod segment. The end of the fourth rod segment away from the third rod segment has a second bent section, which is located below the mounting frame. A connecting frame is connected to the drive structure. The first end of the connecting frame is hinged to the connection between the first rod segment and the second rod segment, and the second end of the connecting frame is hinged to the connection between the third rod segment and the fourth rod segment. The first and second grippers have a separated state and a clamping state. When the drive structure drives the connecting frame to move, it can drive the first and second grippers to switch between the separated state and the clamping state. When the first and second grippers are in the clamping state, the ends of the first bent section away from the first rod segment and the ends of the second bent section away from the fourth rod segment abut against each other.

[0007] Furthermore, the overhead ground wire strand breakage repair device also includes a first arc-shaped block and a second arc-shaped block. The first arc-shaped block is located on the side of the first bending section facing the mounting frame, and the second arc-shaped block is located on the side of the second bending section facing the mounting frame.

[0008] Furthermore, the first preset included angle is between 90° and 150°, and the second preset included angle is between 90° and 150°.

[0009] Furthermore, when the first and second grippers are in the clamping state, the second rod segment is fitted against the first side wall of the mounting frame, and the fourth rod segment is fitted against the second side wall of the mounting frame.

[0010] Furthermore, the length of the first segment is less than the length of the second segment, and the length of the third segment is less than the length of the fourth segment.

[0011] Furthermore, the ratio between the length of the first link and the length of the first segment is between 1.6 and 1.

[0012] Furthermore, the drive structure includes a drive motor and a lead screw, the connecting bracket is provided with a threaded hole, the lead screw passes through the threaded hole, and the drive motor is fixed on the mounting bracket.

[0013] Furthermore, the mounting frame includes a first fixing plate, a second fixing plate, a first connecting block, a second connecting block, and a limiting block. The first fixing plate and the second fixing plate are spaced apart. The first connecting block, the second connecting block, and the limiting block are all disposed between the first fixing plates. The recessed portion is disposed on the limiting block. The first connecting rod is hinged to the first connecting block, and the third connecting rod is hinged to the second connecting block. The connecting frame is movably disposed between the first fixing plate and the second fixing plate.

[0014] Furthermore, the overhead ground wire strand breakage repair device also includes a flight device, which is connected to the drive structure.

[0015] Furthermore, the overhead ground wire strand breakage repair device also includes a control device and a take-up and release device. The take-up and release device includes a winding component and a connecting wire. The control device is connected between the take-up and release device and the flight device, and the connecting wire is connected to the drive structure.

[0016] Applying the technical solution of this invention, the drive structure is mounted on the mounting frame, and the first gripper and the second gripper are respectively mounted on both sides of the mounting frame. The first gripper includes a first connecting rod and a second connecting rod, the second connecting rod includes a first rod segment and a second rod segment with a first preset angle, the second gripper includes a third connecting rod and a fourth connecting rod, the fourth connecting rod includes a third rod segment and a fourth rod segment with a second preset angle, the connecting frame is connected to the drive structure, the first end of the connecting frame is hinged to the connection between the first rod segment and the second rod segment, and the second end of the connecting frame is hinged to the connection between the third rod segment and the fourth rod segment. The first gripper and the second gripper have a separation device and a clamping state. The drive structure can drive the connecting frame to move and can drive the first gripper and the second gripper to switch between the separation state and the clamping state. With the above-described configuration, during repair, the drive structure drives the first and second grippers to separate them. The fixing element is then installed between the first and second grippers and the recessed portion. The overhead ground wire strand repair device is moved so that the overhead ground wire enters the first and second grippers, i.e., the overhead ground wire enters the fixing element. The drive structure then drives the first and second grippers to switch them from a separated state to a clamped state. At this point, the fixing element deforms and clamps the overhead ground wire, preventing it from becoming tangled. This operation is relatively simple, therefore, the technical solution of this application effectively solves the problem of low overhead ground wire repair efficiency in related technologies.

[0030] like Figure 1 , Figure 2 as well as Figures 5 to 7As shown, in this embodiment, the overhead ground wire strand breakage repair device includes: a mounting frame 10, a drive structure 20, a first gripper 30, a second gripper 40, and a connecting frame 50. The bottom of the mounting frame 10 has a recessed portion 11. The drive structure 20 is disposed on the mounting frame 10. The first gripper 30 is disposed on the first side of the mounting frame 10. The first gripper 30 includes a first connecting rod 31 and a second connecting rod 32. The second connecting rod 32 includes a first rod segment 321 and a second rod segment 322. A first preset angle is formed between the first rod segment 321 and the second rod segment 322. The first end of the first connecting rod 31 is hinged to the mounting frame 10. The second end of the first connecting rod 31 is hinged to the end of the first rod segment 321 away from the second rod segment 322. The end of the second rod segment 322 away from the first rod segment 321 has a first bent section 323, which is located below the mounting frame 10. The second gripper 40 is disposed on the second side of the mounting bracket 10. The second gripper 40 includes a third link 41 and a fourth link 42. The fourth link 42 includes a third segment 421 and a fourth segment 422. The third segment 421 and the fourth segment 422 have a second preset included angle. The first end of the third link 41 is hinged to the mounting bracket 10. The second end of the third link 41 is hinged to the end of the third segment 421 away from the fourth segment 422. The end of the fourth segment 422 away from the third segment 421 has a second bent segment 423, which is located below the mounting bracket 10. The connecting bracket 50 is connected to the drive structure 20. The first end of the connecting bracket 50 is hinged to the connection between the first segment 321 and the second segment 322. The second end of the connecting bracket 50 is hinged to the connection between the third segment 421 and the fourth segment 422. The first gripper 30 and the second gripper 40 have a separated state and a clamping state. When the drive structure 20 drives the connecting frame 50 to move, it can drive the first gripper 30 and the second gripper 40 to switch between the separated state and the clamping state. When the first gripper 30 and the second gripper 40 are in the clamping state, the end of the first bent section 323 away from the first rod section 321 and the end of the second bent section 423 away from the fourth rod section 422 abut against each other.

[0031] Applying the technical solution of this embodiment, the drive structure 20 is mounted on the mounting frame 10, and the first gripper 30 and the second gripper 40 are respectively mounted on both sides of the mounting frame 10. The first gripper 30 includes a first connecting rod 31 and a second connecting rod 32. The second connecting rod 32 includes a first rod segment 321 and a second rod segment 322 with a first preset angle. The second gripper 40 includes a third connecting rod 41 and a fourth connecting rod 42. The fourth connecting rod 42 includes a third rod segment 421 and a fourth rod segment 422 with a second preset angle. The connecting frame 50 is connected to the drive structure 20. The first end of the connecting frame 50 is hinged to the connection between the first rod segment 321 and the second rod segment 322, and the second end of the connecting frame 50 is hinged to the connection between the third rod segment 421 and the fourth rod segment 422. The first gripper 30 and the second gripper 40 have a separation device and a clamping state. The drive structure 20 can drive the connecting frame 50 to move and can drive the first gripper 30 and the second gripper 40 to switch between the separation state and the clamping state. With the above-described configuration, during repair, the drive structure 20 drives the first clamp 30 and the second clamp 40 to separate them. The fixing member 1 is then installed between the first clamp 30, the second clamp 40, and the recessed portion 11. The overhead ground wire strand repair device is moved so that the overhead ground wire enters the first clamp 30 and the second clamp 40, i.e., the overhead ground wire enters the fixing member 1. The drive structure 20 then drives the first clamp 30 and the second clamp 40, switching them from a separated state to a clamped state. At this time, the fixing member 1 deforms and clamps the overhead ground wire, preventing it from becoming tangled. This operation is relatively simple, therefore, the technical solution of this embodiment effectively solves the problem of low overhead ground wire repair efficiency in related technologies.

[0032] Specifically, this design enables precise repair of overhead ground wires, making it particularly suitable for power line maintenance in complex terrains such as mountainous areas and rivers.

[0033] like Figure 1 , Figure 2 as well as Figure 5 As shown, in this embodiment, the overhead ground wire strand breakage repair device further includes a first arc-shaped block 61 and a second arc-shaped block 62. The first arc-shaped block 61 is disposed on the side of the first bending section 323 facing the mounting frame 10, and the second arc-shaped block 62 is disposed on the side of the second bending section 423 facing the mounting frame 10. The design of the first arc-shaped block 61 and the second arc-shaped block 62 can better fit the fixing member 1, ensuring stability and safety during the repair process.

[0034] In practical applications, the fitting design of the first arc-shaped block 61 and the second arc-shaped block 62 also helps to reduce additional damage to the overhead ground wire, protect the integrity of the power line, and extend its service life.

[0035] Specifically, the size of the first arc block 61 and the second arc block 62 is 0.25 times the arc of the overhead ground wire.

[0036] like Figure 1 , Figure 2 as well as Figure 5 As shown, in this embodiment, the first preset angle is between 90° and 150°, and the second preset angle is also between 90° and 150°. This angle design allows the first gripper 30 and the second gripper 40 to form a stable clamping force when holding the overhead ground wire, maintaining a good clamping effect even under heavy loads on the overhead ground wire. This design is suitable for repairing overhead ground wires of various specifications. Furthermore, it provides stable repair results for overhead ground wires of different specifications and materials, reducing work delays caused by equipment incompatibility and improving the overall efficiency of power maintenance work.

[0037] like Figure 1 , Figure 2 as well as Figure 5 As shown, in this embodiment, when the first gripper 30 and the second gripper 40 are in a clamping state, the second rod segment 322 is fitted against the first side wall of the mounting frame 10, and the fourth rod segment 422 is fitted against the second side wall of the mounting frame 10. This fitting arrangement ensures the structural stability of the device when clamping the overhead ground wire, reduces safety hazards during operation, and enables the second link 32 and the fourth link 42 to swing.

[0038] like Figure 1 , Figure 2 as well as Figure 5 As shown, in this embodiment, the length of the first segment 321 is less than the length of the second segment 322, and the length of the third segment 421 is less than the length of the fourth segment 422. This length ratio design allows the first gripper 30 and the second gripper 40 to form a wider gripping range when gripping the overhead ground wire, making it suitable for overhead ground wires of different diameters and improving the versatility and adaptability of the device.

[0039] like Figure 1 , Figure 2 as well as Figure 5 As shown, in this embodiment, the ratio between the length of the first connecting rod 31 and the length of the first rod segment 321 is between 1.6 and 1. This ratio design ensures that the first gripper 30 and the second gripper 40 can generate sufficient clamping force when clamping the overhead ground wire, while maintaining the portability of the device, making it easy to move and operate in various terrains, and is particularly suitable for emergency repairs and routine maintenance.

[0040] like Figure 1 , Figure 2 as well as Figure 5As shown, in this embodiment, the drive structure 20 includes a drive motor 21 and a lead screw 22. A threaded hole is provided on the connecting bracket 50, and the lead screw 22 passes through the threaded hole. The drive motor 21 is fixed to the mounting bracket 10. Using the drive motor 21 and lead screw 22, the clamping force of the first gripper 30 and the second gripper 40 can be precisely controlled, avoiding damage to the overhead ground wire or unstable clamping due to excessive or insufficient clamping force. This method is suitable for highly automated power line maintenance operations.

[0041] like Figure 1 , Figure 2 as well as Figure 5 As shown, in this embodiment, the mounting frame 10 includes a first fixing plate 12, a second fixing plate 13, a first connecting block 14, a second connecting block 15, and a limiting block 16. The first fixing plate 12 and the second fixing plate 13 are spaced apart. The first connecting block 14, the second connecting block 15, and the limiting block 16 are all disposed between the first fixing plates 12. The recessed portion 11 is disposed on the limiting block 16. The first connecting rod 31 is hinged to the first connecting block 14, and the third connecting rod 41 is hinged to the second connecting block 15. The connecting frame 50 is movably disposed between the first fixing plate 12 and the second fixing plate 13. This structural design not only ensures the structural strength of the device but also makes the device more stable when clamping overhead ground wires, reducing safety hazards during operation. It is suitable for power line maintenance work in various complex environments. In actual use, this structural design can withstand the test of various extreme weather conditions, ensuring the stability and safety of the equipment in complex terrain and harsh environments, providing a solid guarantee for power line maintenance work.

[0042] Specifically, a bearing seat is provided on the limit block 16, and the lead screw 22 is connected to the bearing seat, which makes the position of the lead screw 22 more stable.

[0043] like Figure 3 and Figure 4 As shown, in this embodiment, the overhead ground wire strand breakage repair device also includes a flying device 70, which is connected to the drive structure 20. The addition of the flying device 70 allows the device to move to the target location in the air without the need for manual climbing of utility poles or the use of aerial work platforms, greatly improving the safety and efficiency of the operation. It is particularly suitable for power line maintenance in hard-to-reach areas such as crossing rivers and valleys.

[0044] In practical applications, the integration of aerial devices enables equipment to respond quickly and complete operations efficiently, even in remote areas, significantly reducing the consumption of human and material resources. It is suitable for rapid inspection and repair of large-scale power lines, especially in emergency situations, where it can quickly locate and repair problems, ensuring the safety and stability of power supply.

[0045] like Figure 3 and Figure 4 As shown, in this embodiment, the overhead ground wire strand breakage repair device also includes a control device 80 and a take-up and release device 90. The take-up and release device 90 includes a winding component 91 and a connecting line 92. The control device 80 is connected between the take-up and release device 90 and the flight device 70, and the connecting line 92 is connected to the drive structure 20. Through the cooperation of the control device 80 and the take-up and release device 90, remote control and automated operation of the device are realized, which not only reduces labor costs but also improves the intelligence level of power maintenance operations. It is suitable for automated inspection and maintenance of large-scale power lines, significantly improving the operating efficiency and safety of the power system.

[0046] In practical applications, this remote control and automated operation mode significantly improves work efficiency, especially in large-scale power line inspections and maintenance. It enables rapid problem location and repair, preventing widespread power outages caused by line faults. The device can also integrate more functions, such as real-time monitoring, data acquisition, and analysis, further enhancing its role in power system maintenance.

[0047] Specifically, the usage process of the technical solution in this embodiment is as follows:

[0048] First, connect the connecting wire 92 to the drive structure, keep the first gripper 30 and the second gripper 40 in a separated state, install the fixing member 1 inside, and fly the flying device 70 above the broken strand. Use the camera to locate the broken strand, and control the control device 80 to control the wire release and take-up device 90 to release the wire, so that the broken strand enters the first gripper 30 and the second gripper 40. Drive the first gripper 30 and the second gripper 40 to move to the clamping state through the drive structure 20, so that the fixing member 1 completely wraps around the broken strand. Drive the drive structure 20 to drive the first gripper 30 and the second gripper 40 to move to the separated state, and control the control device 80 to control the wire release and take-up device 90 to take in the wire. The flying device 70 flies back to the preset position, thus completing one repair.

[0049] The overhead ground wire strand breakage repair device of this embodiment, through its unique first gripper 30 and second gripper 40 design, can effectively and accurately repair broken strands in overhead ground wires, improving repair efficiency and reducing the dangers of manual operation. The addition of the flying device 70 enables remote operation, further enhancing flexibility and safety in practical applications. Furthermore, the coordinated use of the control device 80 and the wire reeling / unwinding device 90 achieves automated repair, reducing labor costs and improving the intelligence level of power maintenance operations. The application of this device is not limited to the power industry.

[0050] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0051] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0052] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0053] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
